Hi,<br>
<br>
Since Python 2.4 (maybe 2.2 or older), fileobj.read(4.2) displays an error and<br>
works as fileobj.read(4).<br>
<br>
>>> i=open('/etc/issue')<br>
>>> i.read(4.2)<br>
__main__:1: DeprecationWarning: integer argument expected, got float</blockquote><div><br>This warning is actually given by the argument parser when "i" gets a Python non-integer.<br></div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
<br>

It should raises an error instead of a warning, it has no sense to read a<br>
partial byte :-) But that should breaks some applications?</blockquote><div><br>This doesn't come into effect until 3.0. <br></div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">

<br>
Well, the real problem is os.urandom(4.2) which goes to an unlimited loop:<br>
<br>
while len(bytes) < n:<br>
bytes += read(_urandomfd, n - len(bytes))<br>
<br>
because read(0.2) works as read(0) :-/<br>
